A type of packer that is designed to be easily removed from the well and reused afterwards. It is part of the tubing string, and the tubing cannot move in the packer.
Retrievable packers are set either by a) weight (J-set or automatic bottom), b) tension, or c) rotation. A conventional retrievable packer has a seal element, packer mandrel, slips, cone, J-shot, hydraulic hold-down button, and backup ring.
